To all' whom it 'may concern: y

. Be it knownthat I, DANIEL HILAIRE' CHI- WERT, mechanician, acitizen of the Republic' of France, residing atNenilly-sur-Sene, near Paris, in the Republic of -Fra.nce,'have invented certain new ainduseful'lmprovements in orAppertainin g tothe Production of Acetylene Gas and Apparatus Therefor, (patented in France February 1,1896, No. 253,620, and 1o August 18, 1896, No. 258,984;in Spain September`5, 1896, No. 19,602; in Italy Sept`ember 4, 1896', No. 42,441; in England August 25, 1896, No.v 2,315; in Argentine Republic october 30,1896,N0. 1,957, in Austria August 31, 1896, No. l16/5/ 256; in Hungary vSeptember' 3, 1896, 7,168, and in'Belgium April 7, 1896, N o. 120,742,') of which the following is .aespexcificatiom This invention relatesto an apparatus for the productionofacetylene gas, and has for its object to furnish means for obtaining in an automatic and regular manner and without increase oftemperature pure gas under constant pressure andin quantities vproporv28, 1896No. 19,059; in Portugalseptember tionate to the consumption, the productionbeing stopped immediately on the cessation of the consumption.

, It consists of anapparatns of simple and practical construction in which calcium carbid is employed in the form of grains ot a given size, as hereinafter shown, said machine being composed, essentially, of a water-reservoir surmount'edby a bell or gasometer coveringsaid reservoirin an air-tight manner and a container for crushed carbid fixed rigidly to the reservoir and locatedwithin the bell and-independent of the same, said container being provided at its base with a valve adapted by the movements 'of the bell to -be oper ated to admit the carbid to the reservoir.

I have found that'in order tc realize the i. advantages hereinb'e'fore mentioned the calcium` carbid must first be crushed and sieved in such a way as to bring it to a condition of granules approximately of the size of a grain of wheat. The feed or fall of granules of this size is easily eiec-ted and may 'be "regulated their Weight is sufficient `to cause them to fall to the bottom of the reservoir, in which thel mass'ofwater absorbs the heat developed and produces a washing of the gas, which insures its purification. Finally the smallsize of the granules allows chemical action to be immediately developed, so that 'the productects their internal parts and prolongs the discharge of gas for a considerable time after the feed has been stopped. It 4will be seen, therefore, that the size of the granules of cart-ions hereinbefcre stated.

In the accompanying drawing the ligure represents a vertical section of the apparatus.

apparatus is composed of arreter-reservoir A, surmounted by a bell or gasometer B, the lower part of which is immersed in an annular chamber c filled with water, but independent of the water-reservoir A, which latter is provided with a supply-pipe a, a discharge-pipe a', and a gas-withdrawal pipe a2. The calbell'and supported by bars orbrackets fixed to the reservoir A. Said container carries on its upper part rollers b, which serve as guides for the bell B, and is provided in its lower conical partjwith a valve E in the form of a cupel, the spindle of which valve 'is guided in a sheath or holder'e, fixed to the carbid-conbeveled or tapering edge of the valve bearing `on a washer, of india-rubber or'other suitable flexible material, which forms a seat. The

valve is operated by a lever?, pivoted' on a with precision by the valve,'and, moreover,

cium-carbid container D is placed inside the tion of gas ceases immediately the feed of the become coated with a skin of lime which pro'- bidv is effectively determined by the condi- Referring to'the drawing, the improved tainer 1), or in any other suitable manner, the l fixed support f and having at one of its ends a counterweight G, intended tc keep the valve normally closed. The other end of the lever F is suiciently prolonged to be engaged by an annular projection or strip H, fixed on the tirely free in its upward and d )wnward movements, causes, each time that it descendsa certain uantity of the gran .iles of`carbid to fall into he water and 'cons equently the production of a corresponding volume of gas, 'which then forces the bell tf t rise immediately. The valve E then closes imr iediately under theaction of the weight G, and the production of acetylene is arrested unti the consumption of the gas produced cause; the bell to again descend and to bring about a fresh fall of ear; bid into the Water. Practici .,shows that undef these conditions the movements of the bell B are very slight, so that the p vcssure of the gas produced, which escapes b) the gas-pipe a2, maybe considered as being constant during the working of the apparatun.

It will be seen that in the ydrawing the bell B is provided at a point Aabove the screw-stopper d of the carbid-container with a tubular chamber I, opened at its lower end and closed above by a screw-stopper t'. This chamber is threaded on its periphery an-l may thus be raised or` lowered by means of a-hand-wheel,

or in any other suitable manner, in a screwthreaded collar arranged ou the bell. When it is desired to introduce granulated carbid into the container D, the said chamber I is turned in such a way as to cause it to descend until its lower edge comes to rest and forms a tight joint, with an india-rubber washer (Z2 arranged for this purpose around the stopper d" of the container. The two ntoppcrs CZ and 'i are then unscrewcd, and the carbid is introduced by means of a funnel or hopper.` This operation terminated, it is suficientte replace the two Stoppers and to cause the chamber to rise into its upper position to render the apparatus ready for working.' In this manner ne can escape from the bell, :1nd the operation is elleetcd promptly and `without allowing any disagreeable oder to es zape.

It is evident that instead of using a Screwthread formed on the periphery of the cholinber I any other suitable arrange ment may be employed for causing the said chamber to telescope in the interiorof the bell for the purpose stated.

I declare that what I claim is- .1.. In an apparatus for producing acetylene `gas comprising a water-reservoir and a bell or gasometer covering said reservoir in an airtight manner and including a fixed container for crushed carbid, th'e combination therewith of a valve E in the form of a cupel and ar- 'rangcd and guided in the discharge-orifice of the container and o c rated by means oit-a hinged and counterweighted lever F, the end of which lever is adapted to be engaged by an annular projectionA or strip 1I on the interior of the bell, substantially as hereinbefore described and shown. 4

2. 'In au apparatus for producing acetylene gas comprising a water-reservoir, a bell or gasometer covering said reservoir in an airltight manner and including a fixed container for crushed carbid, the combination therewith of a movable chamber I by means of an airtight joint in 'an opening formed in the bell above the filling-orifice of the container in such a way as to form when lowered artight joint on the said reservoir and of the Stoppers i, d', adapted to the said chamber and con tainer respectively for the introduction of the crnshed-earbid-imoelle-container, substantially as hercinbefore described and shown.

3. ln an apparatus for producing acetylene gas, a water-reservoir A, a bell or gasometer B covering the said, reservoir, a container D forcrushed carbid fixed tothe reservoirA and having rollers b for guiding. the bell, a valve E guided bya sheath or socket c arranged vertically in the center of the orifice for discharging the carbid, a chamber I screwthreaded at the top of thc bell to form an airtight joint at the top of the container and.

Stoppers 1T, d', arranged in the chamber I and container l) respectively, substantially as described and shown.

In testimony whereof I have signed my name to this specification inl the presence of two subscribing witnesses.
